  • Amélioration de la version de base

    13 septembre 2013

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Resolving rtmp stream url from Adobe Flash container

    14 avril 2013, par Mustafe

    How can a rtmp stream url be retrieved completely with its playpath and be played with ffplay/avconv from a flash plugin. In embedded flash code below rtmp address exits (rtmp ://live.atv.com.tr/atv) , however it does not work with avplay since it needs playpath.

    /i.tmgrup.com.tr/p/flowplayer.controls.swf"},"influxis":{"url":"http://i.tmgrup.com.tr/p/flowplayer.rtmp.swf","netConnectionUrl":"rtmp://live.atv.com.tr/atv"},"ova":{"url":"http://i.tmgrup.com.tr/p/ova.swf","autoPlay":true,"overlays":{"regions":[{"id":"Reklam","verticalAlign":"bottom","horizontalAlign":"right","backgroundC...0,"style":".smalltext { font-style: italic; font-size:10; }"}]},"ads":{"notice":{"show":true,"region":"my-ad-notice","message":"<p class="\&quot;smalltext\&quot;" align="\&quot;right\&quot;"> Kalan süre : _countdown_ saniye.</p>"},"schedule":[{"zone":"5","position":"pre-roll","server":{"type":"direct","apiAddress":"http%3a%2f%2fad.reklamport.com%2frpgetad.ashx%3ftt%3dt_atv_canli_yayin_preroll_800x700%26vast%3d2"}}]}}},"playerId":"live","playlist":[{"eventCategory":"Canli Yayin","url":"atv3","live":true,"provider":"influxis"}]}" name="flashvars">

    Problem Solved : Using wireshark (network analyzer) is much more effective to retrieve paramaters like rtmp url, playpath...
    Edit2 : Some urls are also embedded in scripts files rather than directly in flash object, this variables are used in flash object above, later.

  • Revision ed2dc59c1b : Integral projection based motion estimation This commit introduces a new block

    Integral projection based motion estimation

    This commit introduces a new block match motion estimation
    using integral projection measurement. The 2-D block and the nearby
    region is projected onto the horizontal and vertical 1-D vectors,
    respectively. It then runs vector match, instead of block match,
    over the two separate 1-D vectors to locate the motion compensated
    reference block.

    This process is run per 64x64 block to align the reference before
    choosing partitioning in speed 6. The overall CPU cycle cost due
    to this additional 64x64 block match (SSE2 version) takes around 2%
    at low bit-rate rtc speed 6. When strong motion activities exist in
    the video sequence, it substantially improves the partition
    selection accuracy, thereby achieving better compression performance
    and lower CPU cycles.

    The experiments were tested in RTC speed -6 setting :
    cloud 1080p 500 kbps
    17006 b/f, 37.086 dB, 5386 ms ->
    16669 b/f, 37.970 dB, 5085 ms (>0.9dB gain and 6% faster)
